4 Claims.

This invention relates to plate distilling columns for columnarstilis, especially adapted for distillation or rectification of ethyl alcohol and other similar products, and has for the primary 5 object the provision of a device of this character which is equipped with novel constructed plates to cause double acting baiillng or refluxing of the product so that the number of such devices in a column may be materially reduced and still efllciently handle a given load, thereby permitting a column to be reduced in height and manufactured at a low cost.

With these and other objects in View, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a fragmentary side elevation, partly in section, showing a column constructed in accordance with my invention.

Figure 2 is a sectional view taken on the line 2-4 of Figure 1.

Figure 3 is a fragmentary sectional view taken on line 3-3 of Figure 2.

Figure 4 is a plan view showing one of the baffling units.

Referring in detail to the drawing, the numeral I indicates a vertically arranged casing of cylindrical shape having connected to its upper end an outlet pipe 2 adapted for connection to a condenser (not shown). The casing l is composed of a plurality of superimposed detachably connectedannular sections and located between said sections are plates 3 forming the sub- Ject matter of the present invention. The fasteners employed to connect the sections of the casing together also secure the plates 3 in position.

The casing I and plates cooperate in forming the column and the latter may be equipped with as many plates as the capacity of the still will require. These plates are set one over another common in an ordinary plate distilling column generally found in alcohol distilleries. Each plate has a plurality of circular openings 3' formed centrally of substantially hemispherical mounds l. The mounds form an integral part of the plate and also provide seats for upper and lower groups of balls or spheres 5 and 8. The lower groups of balls are held in contact with the mounds by curved supporting plates I connected 56 by tie bolts 8 to caps 9 which retain the upper groups of balls 5 in engagement with the mounds 4. The tie bolts 8 extend throughthe openings 3'. The balls, mounds, plates and caps form to each plate 3 a-plurality of baifling or reflux units. The upper balls 5 of each unit are grouped annuiarly, also the lower balls 6 are arranged annularly in inner and outer groups, as shown in Figure 4. The balls 5 are closely related to each other and also the balls 6 of the outer and inner series are closely related and the outer series of balls 6 may be smaller in size. The balls 5 and 6 are constructed of porcelain, china, metal or any other material suitable for the purpose.

Each plate is equipped with a drain III for maintaining liquid in the column between the plates at a selected depth so that the balls 5 will be partially submerged.

Each baflling unit described can be easily taken apart, and the column in entirety may be readily repaired, cleaned or otherwise cared for. The corralling of the balls as described and shown provides to each plate a plurality of efilcient baffiing devices. The mounds or projections 4 bring about a reasonably deep pool of liquid on the upper side of the plate during the use of the device. Even if a pool of maximum depth were obtained by having these mounds or projections very prominent there can be no pressure created in any of the chambers of the distilling column due to too much condensation taking place and be-'- cause of the atomizing of the liquid passi g through the baflling units in which the-vapors are bubbled by the balls 5. It is to be noted that each mound or projection 4 is a truncated cone with an opening which allows the vapors to expand at its base and then eject the same at a high velocity therefrom. The baflling units are well distributed on the surface of the distilling or rectifying plates 3. The bubbling takes place throughout the upper surface of the plate and due to this arrangement the whole standing liq uid is kept in uniform, vigorous agitation, whereby sedimentation is prevented and a thorough mixing of the distilled liquid is accomplished. The balls 6 and plate I of each battling unit form a trap or separator which prevents vapor traveling in strong current from carrying over into the standing liquid on the upper side of the plate 3.

with vapor traps provided to the plates as described, the space from plate to plate in the column need not be so high as would be the case without them. The bafliing of vapors prior to their entrance into an opening, a salient feature in my invention, warrants the construction of low type distilling columns. The halls arranged in the manner described insures the production of ell fractionated distillates. They rectify vapors before they can mix with those evolved from a liquid of lower boiling point. The balls 8 held by the mounds 4 and cap 8 oflfer a tremendsusly large surface on which gases may come in contact with the liquid they have to heat and to which they yield their heavier constituents through condensation. Due to the arrangement of the baflling unit all standing liquid is kept in constant agitation by the bubbling of gases or vapors through the spaces between the upper balls I.

Having described the invention, I claim:

1. A device of the character described comprising a horizontally arranged plate having an 01!- set provided with an aperture centrally thereof, spherical shaped elements engaging opposite faces of the offset, and means supporting said elements in engagement with the onset.

2. A device of the character set forth comprising a horizontally arranged plate having a portion thereof oifset to form a mound provided with concave and convex faces, and an aperture centrally thereof, balls 0 18881118 said faces, and means supporting said balls in engagement with the faces of the mound.

3. A device of the character set forth comprising a horizontally arranged plate having a portion thereof offset to form a mound provided with concave and convex faces, and an aperture centrally thereof, balls engaging said faces and arranged in groups of annular formation, and means supporting said balls against said faces.

4. A device of the character described comprising a horizontally disposed plate having an offset providing a mound. said mound having concave and convex. surfacesand an aperture arranged the convex surface of the ground, and a cap se- 20 cured to the tie rod and supporting the balls against the convex surface of the mound.
